Managed to clock ram up to 600mhz 5-3-3-3 2T but with even further tighten the sub timings even more but had to loosen CAS from 4 to 5 in order to keep vdimm at 2.5v bios set ceiling (within OCZ warrantied max vdimm of 2.52v)

Damn impressive with the sub-13-30 mate especially with cpu-z open, I'd be willing to bet that without cpu-z open you could take a couple of seconds off that time too. Easily one of the best tweaked striker setups around - no joke.

So only could manage 1M times for X6800 @4000mhz at 1.6v (1.57v load) on Asus 680i Striker Extreme. Higher vcore just meant reboots in windows under load (maybe vdroop too much at higher vcore like on P5B Deluxe ? )

Super Pi 1M

Everest Bandwidth with 42.7ns latency

But at much lower vcore of 1.56v idle/1.54v load, coretemp reports more reasonable idle temps and I can manage 3967-3972mhz at 1.56v idle for 32M with lower mem clocks but once hit 600mhz 5-3-3-x timings seems tight sub timings cause instability until I drop cpu down to 3950mhz at 1.57v idle!
